Hi,
I am trying to use package dyn together with loess. I have the following
issue in the code below when I use "predict" while specifying the "newdata"
argument.
Any help is welcomed. Thanks in advance.

> y <- ts(1:12, start = c(2000,2), freq = 4)^3
> x <- ts(1:9, start = c(2000,3), freq = 4)^2
> do<-cbind(x,y)
> rm(x)
> rm(y)
> y.loess <- dyn$loess( y ~ diff(x) ,data=do)
> predict(y.loess)
